If I could weigh-in for a moment. I'm delighted to hear the maker is standing behind his brush. That's expected.

Looking at the knot, I doubt that too little adhesive was used. Generally speaking, you want a very thin layer of adhesive--just enough to provide an even coating on the base of the socket. That will create the strongest bond. (That seems counter-intuitive, but it's the consistent message I hear from adhesive manufacturers' engineering staffs. It also minimizes the chance of adhesive overflowing into the hair, which can ruin a knot faster than anything else I know of.) The problem comes when the adhesive doesn't have something to hold on to. Why is that? It's because many (most?) knot plugs are smooth, even glossy. So there's not much for the adhesive to grab onto. From the photo, I would guess that's probably the case.

Fortunately, there's a very simple solution, if you decide to keep the brush.

I would first level the knot plug with a piece of 120-180 grit sandpaper. That should not only remove the remaining adhesive and--more importantly--give the new adhesive something to latch on to. A little over-the-counter epoxy will do the trick. You can go with marine epoxy, if you want, but I don't know that it's really necessary. (Candid comment: I use a high-grade commercial epoxy on our brushes, but I've also advised a number of folks who've experienced problems like yours and never had an issue.)

Well, at 4:10 PM a return label was sent, followed by a call to apologize for the failure. I'm sending it back. A $20-$30 brush, I would probably just glue it back, but a $215.00 brush.
It has to go back. The seller is taking care of it and that makes me happy. Now, what to buy ? I'm thinking another Plisson..........

A Plisson synthetic?

Got one. Think I'll get the European White I think they call it. Not the Russian Grey. They have their own system for grading badger.

STUPID IS AS STUPID DOES... I really liked this brush....soooo I ordered another one...
Can/will it fail again ? Only time will tell. Surely the same guy, same day, same epoxy batch or whatever,
will not strike again...

I would hope that third time is the charm for you zipper. To have two separate is really unlucky. I also had a very high end Italian brush have the knot separate on me. I ended up keeping it instead of asking for a replacement as I loved the knot too much to risk getting something different. Did you buy the most recent one new or used? The picture in the acquisition thread looks great in regards to the knot.

It's new. It's such a fantastic knot. The Ebony wood handles on the other two were so smooth and the grain of the Ebony was fine and tight. Just a great
brush except for that one problem.

To update, I did not use it everyday in July......
But it looks like it's going to go the distance...
It's a really great brush and has such "presence"...…..
I've lost two hairs, that's good for such a dense knot.

Really pleased you decided to stick (no pun intended) with the SV brush. This is the first time I’ve seen anything regarding quality issues with their brushes. I’ve owned one for 18 months with no issues.

I’ve owned and used most of the high end brushes and the SV is still head and shoulders above the rest. I don’t like to use it all the time as I don’t want it to lose it’s ‘specialness’ (is that even a word?). I’m sure you know what I mean? I have plans to buy another one soon.

Good luck with your brush and I hope you have many trouble free years together.
